4D Tracking

1 Tracking clustering, seeding and finding

Tracking performance (purity, efficiency, CPU time)
minimum pT threshold
Large-R tracking

2 Object performance: b-tagging, charm-tagging, tau-tagging, PU suppression, Missing ET, particle flow

• b-tagging
• charm-tagging
• tau-tagging
• PU suppression
• Missing ET
• Particle flow

3 Layout studies

Mechanical, electrical (power), radiation, and data-transmission constraints for either a second layer replacement or a dedicated third timing layer. Consider potential technologies for sensors, electronics, and data-transmission. Study barrel and disk options separately.

5D Calorimetry

4 Vertex t0 reconstruction

• t0 resolution and efficiency
• Applications:
  o t0 for HGTD
  o PU suppression
  o LLP search (displaced photons/jets)

Speaker: Doyeong Kim

5 Single pion studies

• time evolution/structure of pion showers
• response vs time
• neutron component identification

Speakers: Doyeong Kim, Zahra Farazpay (Loisiana Tech)

6 Space-time structure of hadronic showers

• Response vs time
• overlapping showers
• time-aware GNN PFlow reconstruction

Speaker: Zahra Farazpay (Loisiana Tech)

7 Higgs Factory calorimeter timing studies

Electronics and Sensors: 4D/5D techniques

8 LGDAs

Speakers: Christopher Kenney (SLAC), Julie Segal (SLAC)

9 28nm CMOS TDC ASIC

Speakers: Bojan Markovic (SLAC), Larry Ruckman (SLAC)
